Conexão da aplicação com o servidor local

Como não consegui solução, continuei desenvolvendo com a API do Hero http://cdc-react.herokuapp.com/api/autores mas ao tentar gravar o evento, depois de implementadas as funções do envia form ele me retorna o erro:

POST http://cdc-react.herokuapp.com/api/autores 500 (Internal Server Error)

Oi Pedro, vamos lá! Pensando no servidor local, que é o melhor caminho. Depois que vc roda o jar, tente acessar o endereço http://localhost:8080/api/autores. Como não tem nada lá, deve retornar um json vazio.

Para rodar a app do react, abra outro terminal ou outra aba de terminal, navegue até a pasta do projeto e execute o npm start.

Fala Alberto,

Ainda não. Retorna o erro:

Failed to load resource: net::ERR_CONNECTION_REFUSED

Fiz como sugeriu, com dois prompts e na pasta node_modules.bin\cdc-admin.

Alguma outra ideia do que possa estar havendo? Obrigado.

Mas esse erro não aconteceu quando vc tentou acessar o endereço que eu te pedi, né? pq não parece ser um erro relacionado ao java. Na url da api, especificamente, qual erro aparece no terminal? Lembre, é para ir no navegador e acessar http://localhost:8080/api/autores

Fala Alberto, não entendi sua pergunta (Na url da api, especificamente, qual erro aparece no terminal? ). Tanto no console, como no navegador, me retorna o erro:

Failed to load resource: net::ERR_CONNECTION_REFUSED

No caso do navegador, me mostra a mensagem de que não é possivel acessar o site. Mas o que estou estranhando é que o .jar carregou perfeitamente, além disso o npm está inicializado.

Estou exatamente no vídeo 02 da aula 03: Atualização de estado componentes

Fui executar o mesmo comando informado pelo instrutor do curso a partir do JAR disponibilizado no link:

https://bit.ly/jar-api-curso-react

java -jar cdcreact-1.0.0-SNAPSHOT.jar

Mas estou obtendo o seguinte erro:

https://gist.github.com/araujodavid/b0f0e72ce5625005889db10518fba2a8

Percebi que no log é apresentado algumas coisas referentes ao MySQL. É preciso ter o MySQL instalado para rodar o servidor? Se sim, onde isso foi especificado no curso? Não encontrei.

Grato.

David, Sua dúvida em relação ao MySQL também é a minha. Não tinha nem abordado essa questão mas no meu caso não instalei ele ainda, tentei desenvolver sem ele. Não sei se talvez por isso, não estou conseguindo conexão com o servidor.

Esse script do erro que você colocou o link, pelo que entendo acho que é o JAVA rodando "de boa", não? Acho que não é um erro, caso seja está acontecendo comigo também.

Olá David, você pode usar a API do Heroku(http://cdc-react.herokuapp.com/api/autores), mas caso deseje usar a API fornecida no curso é necessário sim ter o MySQL instalado.

Um dos exercícios da Aula 3 mostra em detalhes como fazer: https://cursos.alura.com.br/course/react/task/19739

Bons Estudos

Oi Jefferson, obrigado pelo esclarecimento. Uma sugestão então é colocar estes requisitos logo no item: https://cursos.alura.com.br/course/react/task/19598

Grato.

Exato Pedro, o link que eu coloquei é o Java rodando, mas não encontra o MySQL.

Oi gente, a explicação ta aqui => https://cursos.alura.com.br/course/react/task/19739

Precisa sim do mysql.. Tentei deixar o ambiente o mais próximo dos que vcs vão encontrar no mercado.

Olá Alberto, desculpe pela demora.

Instalei o MysQL no Windows. Em seguida, rodei o comando java -jar jar-cdc-react.jar e em paralelo o npm start. Aparentemente rodou tudo de boa, mas o console ainda me retorna o erro:

Failed to load resource: net::ERR_CONNECTION_REFUSED

Abaixo o que é gerado ao tentar executar o java -jar jar-cdc-react.jar:

Minha dúvida é que inseri o diretório do .bin do MySQL na variável Path, além de conferir, através do comando mysql -u root -p, se ele estava instalado corretamente.

Pode me ajudar? Obrigado.

O seu banco tem senha? se tiver, faz assim:

java -Dspring.datasource.password=suaSenha -jar jar-cdc-react.jar

Funcionou Alberto! Está exibindo a lista e gravando os dados. Obrigado e até a dúvida seguinte, rs!
